. BEREICH FITTING.

Application tiled- December To all whom it may concern:

VBe it.known that we, Rioiiaiio R. BLoss' and WILLIAM SoHwmrLEiN, citizens of the United States, residing at Parkeisbiirg, in l the county of Wood and State of West Virinia, have invented certain new and useful inproveiiients in Derrick Fittings, of which the following is a s eeification. 'Y

This invention re ates to derrick fittings, i and itl comprises a' member iliade iii two sections and adapted to be secured around` the abutting ends of adjacent leg sections said members being secured to the horizonte girtlis forming a part o the derrick and emracing said eg sections, when in position, and diagonal braciiiu' members adapted to be secured to said mem rs.

In the present invention, we have produced a dei'rick fitting by means of which a derrick may be speedily erected and disassem;

bled. Bolts ma be employed to secure the;

leg sections in t e members forming the fit-V ting, but theother parts are lield'in position by pins or other suitable fastening-means 25 which ma be quickly removed. The two members orinin a fittin are permanently secured to the orizonta 'rths, lthereby eliminating one ofthe usual :listening members that has to be removed in disassembling The fixed ends of the horiziontal giiiths pro-` vide diagonal bracing in the horizontal plane at the different leg sections. The fittings being permanently secured to the hoi'i- J5 Zonta-l girths, vit is possible to developthe full strength of the girth as a beam. l eil resisting compression strains, the horizontal girth acts as a column with fixed ends. When resisting the tendency of the derridk to be 4e distorted from a true rectangular shape, the girth acts as a beam fixed at both ends.

In the accompanying drawings, ive-have shown one embodiment of the invention. In this showing: Figure 1 is a side elevation of a portion of a derriek showing the fitting ap lied,

Figure 2 is a vertical sectiona` view, and,

Figure 3 is a horizontal sectional View on line 3-3 of Figure 1.'

Referring to the drawings, the upper leg section 1 and the lower leg section 2 are arranged with their ends abutting eachother in the usnai manner. A member 3, prefer- 24, 192i). Serial No. 432,916.

ably tubular in constructive-n, is erinai-iently 'or otherwise secured to either t e upper or lower leg section and projects beyond theV end thereof. This member facilitates as- ,senibliiig, aiidwlien the structure is assembled, its projecting portion extends within the ,end of the abutting leg section and serves as' a bracing' means. p

Asffisffusiiahiri a den-ick construction, a pair ofhorizontal girths 4 and 5 are'arranged the" abetting ends of the leg sections v1 and 2. The dei-rick fitting comprises afpaii of members 6 ,and 7, one of which is secured-to each of the horizontal girths respeetivelyegglfhe fittings are plrovided Iwith sockets onreces'ses 8,in whic the ends of vthe girthsare adapted to be arranged, the v4ends of the girths being permanently secured 'in said sockets in any suitable manner.v Each member of the fitting comprises substantially a semil'circular ortion 9 adapted to embrace la portion of eac of the leg sections. A bolt V10, 'may be assed through the fitting members 6 and andthe projecting portion of the bracing member 3, together with the leg section teleseo ing over the end thereof, to -secure the fittings to the legs and the legs to each `other thereby providing positive means of transmitting axial tension from the one leg section to the other. The bolt 10 is provided with a.f nut 11 arranged on its threaded end, and apip 12 is'adapted to be arranged in a pair ,of ears 13, formed on the fitting to prevent. tlieniit from turning when in position. As shown, the pin'is arranged vertically and is held in place by gravity. The lother fitting ineinberjs provided with a pair opro'jeetions or lugs 13', adapted to prevent the bolt fnlom turning when in posi-l tion. l

The socket 8 andthe semicircular portion by a pair of` openingr 17, in the end of the bracing membei'. The pin is provided with an opening adapted to receive a locking pin 18.

By means of. the construction shown, a

simple and eiiicient fitting is ,provided by' means of which a derrick may be readily astdbetaken as a where the girths are rnerly received in sockets in the fitting. 'lhe'ronstructiou is further advantageous, in that the two mem- :bers forming a fittingr are always in proper 'position and are notlreachlv' lost, as is the' caseii'heie a relatively small member forming-.a"pnrtof thettingis not permanently secured to one of the'elements of the. derrick.

Itis-tobe understood thatftheform of ominvention herewithshownand described is preferred example of the same, an'rithat various changes in' the unmber of bolts and pins. shape. size. and arrangement of parts may be resorted to without departing from the spirit of Vthe invention orf the scope of the sulijoined `rlaims.

Having'thus described our invention. we claim:

1; The combination with a derrich haring horizontal girths arranged substantially at right -angles'to each other. and legs formed in opper and lower sections having their lion and the upper leg abutting ends arranged near said girths, of a derriclr fitting comprising a tubular member-projecting into the adjacent en'ds of said leg sections. a pair of substantially semicylindrical members mounted 'onsaid girths and surrounding the adjacent ends of said leg sections-and a boltl passing through said semicylindrical members, said tubular memsec-tion.

2. The combination with a derrick having horizontal girths arranged substantially .at right angles to each other` and legs formed in upper and lower sections having;r their ahuttiuf: ends arranged near said lgrirths. of :i derriclr fitting! comprising a tu'hnlar memher projecting into the ad'acent ends of said leg sections. an embracing means mounted on said girths and surrounding! the adjacent ends of said leg sections` through said embracing means. said tubular member. :md the upper leg,r section'.

In testimony whereof we aliix our signatures in prescrire of two witnesses.
